Description

ST9100C is a single channel timer designed primarily for control of a single heating zone or combi boiler application. It is suitable for mains low voltage or potential-free switching of the heating load. This model is a 7 day timer that gives great flexibility offering up to three on/off switchings per day additionally each day can be programmed differently. Ideal for combi boiler installations or multi zone systems when the user has different heating needs from day to day. ST9100C can be set to 5/2 day or 1 day programme during installation. All ST9100 models incorporate the Line of Text (LoT) display that gives clear plain English instructions whenever any button or slider is used. This means that installers customers and users can operate all of the controls reliably without needing to find an instruction manual. ST9100C also features a 'Holiday' button allowing the user to switch off their heating for a specified number of days (1 to 99) while they are away from home. This model has superceded the ST6100C.

Reviews

Buying guide: Heating Controls

Heating controls switch a central heating system on and off and hold rooms and hot water at the right temperature. This category covers room thermostats, programmers and time switches, programmable and smart thermostats, wireless thermostats with boiler receivers, smart radiator thermostats, motorised zone and diverter valves, valve actuators and wiring parts.

Types of control

Programmers and time switches: set when the heating and hot water come on.
Room thermostats: switch the heating off when the room reaches the set temperature. Programmable room thermostats combine time and temperature control in one unit.
Wireless and smart controls: a wireless thermostat talks to a receiver wired at the boiler. Smart thermostats add app control, and some learn your routine and start the boiler at the right time to reach the set temperature.
Motorised valves: on systems with a hot water cylinder, either one 3-port valve or a pair of 2-port valves directs heated water to the radiators, the cylinder or both. Match the pipe size and valve type when replacing one.

Regulations

In England, Approved Document L sets minimum controls when a gas or oil boiler is replaced: a programmer, a room thermostat, thermostatic control in each room (usually TRVs on every radiator except in the room with the main thermostat) and boiler interlock, so the boiler and pump switch off when nothing calls for heat. Systems with a cylinder also need separate hot water timing and a cylinder thermostat. A replacement gas combi boiler also needs one extra measure, such as weather or load compensation, flue gas heat recovery or a smart thermostat with automation and optimisation.

Mains wiring to controls and valves is electrical work, and some electrical work in homes is notifiable under Part P. For radiator valves, see thermostatic radiator valves, or browse radiators.
